Delhi records two good air quality days in 2017

Despite the toxic haze that engulfed Delhi for more than a week in November, the national capital breathed comparatively cleaner air this year than it did in 2016. The air quality was "severe" for eight days in 2017 as against 26 the previous year, according to data from the Central Pollution Control Board (CPCB).
